How works the scoring of rating of yahoo games?

Question

Do the scoring of dominoes depends from the opponents rating? What is the math?

The better the player rating the more your rating will increase if you win a rated game with them.  However, on Yahoo there are many cheats and stallers who only care about increasing their rating, via cheating and not thru good game play.
